The &$1 or &ontroller $rea 1etwork is an advanced serial bus system that efficiently supports
distributed control systems. It was initially developed for the use in motor vehicles by Robert
Bosch GmbH, Germany, in the late 1980s, who hold the CAN license. CAN is most widely used
in the automotive and industrial market segments. Typical applications for CAN are motor vehi-
cles, utility vehicles, and industrial automation. Other applications for CAN are trains, medical
equipment, building automation, household appliances, and office automation.
The development of CAN began when more and more electronic devices were implemented into
modern motor vehicles. Examples of such devices include engine management systems, active
suspension, ABS, gear control, lighting control, air conditioning, airbags and central locking. All
this means more safety and more comfort for the driver and of course a reduction of fuel consump-
tion and exhaust emissions.
